UNITED STATES PATENT OFFICE.

MYRON OOLONEY, or NEW HAVEN, CONNECTICUT, ASSIGNOR To JAMES HENRYMCLEAN, or sT. LOUIS, MISSOURI.

CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 225,464, dated March16, 1880. Application filed February 10, 1879.

To all whom it may concern:

Be it known that I, MYRON GoLoNEY, of the city and county of New Haven,in the State of Connecticut, have invented a certain new and usefulImprovement in Cartridges, of which the following is a specification.

My cartridge consists of three members, to wit: a cylindrical case forthe powder, preferably grooved circumferentially at its rear end; aprojectile formed with conical front and rear ends, a cylindrical centerportion and a stem or tail projecting backward in the line of its axis;and a uniting plug or sabot, preferably of wood, reamed out in front toreceive the conical rear of the ball, and perforated in its axis toreceive the stem thereof, and at back formed with a rabbet to fit withinthe front of the cartridge-shell.

In order that my invention may be fully understood, I will proceed todescribe it with reference to theaccompa-nying drawings, in which-Figure 1 is a side elevation of the parts of the cartridge detached.Fig.2 is a longitudinal section of the complete cartridge.

A represents a cylindrical case, of paper, sheet metal, or othermaterial, intended for the reception of the powder, and having acircumferential groove, a, at its rear end, to adapt the cartridge to bepassed laterally between suitable jaws in the breech of the arm, whichjaws, engaging in said groove, will hold the cartridge firmly againstthe stroke of the firing-pin. The base of shell A is also preferablyformed with a customary nipple or fulmi nate-recess, a, for center-fire;but, if preferred, the invention may be embodied in a rim-firecartridge.

The projectile O is formed with a conical front and rear and acylindrical center part, as shown, and from the apex of its conical rearend extends a stem, 0, in line with the axis.

The central uniting plug or sabot, B, is formed in front with a cavityto fit the rear end of the )rojectile C, and is bored in line with itsaxis to receive the stem 0, the periphery of the plug or sabot B beingprecisely flush with that of the projectile O. p

The rear of the plug or sabot is formed with a groove or rabbet, b, toadapt it to fit within the front of the powder-case A, within which itis securely glued when said case is tilled.

The plug or sabot B maybe made of paper, but preferably of wood. Thepowder-case A is of paper or sheet metal or other material.

The projectile (3 may be of any metal preferred.

I am aware that projectiles have before been made with a cylindricalcentral part and conical front and rear; also, that projectiles ofdifferent forms have been made with a rearwardly-projecting centralstem.

Special advantages result from my mode of forming the ball with acylindrical center to guide it accurately through the bore, andcombining therewith the conical front and rear, to lessen atmosphericresistance, and the rearwardly-projecting stem, to prevent deflection.Further advantage results from combining with a ball, G, shaped asspecified, a hand or sabot, B, of the form shown, fitting the conicalback of the ball, extending the cylindrical outer surface to thenecessary length, attached to the ball by the stem and serving for theattachment of the cartridge shell or case.

Having thus described my invention, the

following is what'I claim as new and desire to secure by Letters Patent:

1. The projectile O, constructed as herein described, with conical frontand rear, cylindrical center, and a rearwardlyprojecting stem, 0.

2. The combin ation of the projectile G,formed with a cylindricalcenter, conical ends, and a rearwardly-projecting stem, and the band orsabot 13, formed with a cylindrical periphery flush with that of thehall, a shoulder or rabbet for the attachment of the case A, and acentral aperture to receive the stem 0, by which it is attached to theball.

MYRON OOLONEY.
